If you need to store the hash in a variable during a script, you can use

last_commit=$(git rev-parse HEAD);

Or, if you only want the first 10 characters (like github.com does)

last_commit=$(git rev-parse --short=10 HEAD);

I got this error when I dynamically read data from a WebRequest and never closed the Response.

    protected System.IO.Stream GetStream(string url)
    {
        try
        {
            System.IO.Stream stream = null;
            var request = System.Net.WebRequest.Create(url);
            var response = request.GetResponse();

            if (response != null) {
                stream = response.GetResponseStream();

                // I never closed the response thus resulting in the error
                response.Close(); 
            }
            response = null;
            request = null;

            return stream;
        }
        catch (Exception) { }
        return null;
    }

Copy all order entries of home folder .iml file into your /src/main/main.iml file. This will solve the problem.

In Visual Studio 2012, 2013, 2015, you can also do it with Web Essentials, just right click the files and from context menu > Web Essential >> Diff selected files:

Edit: It's now available as a separate extension

Well, from sourceTree I couldn't resolve this issue but I created sshkey from bash and at least it works from git-bash.

To compare each item with the next one in an iterator without instantiating a list:

import itertools
it = (x for x in range(10))
data1, data2 = itertools.tee(it)
data2.next()
for a, b in itertools.izip(data1, data2):
  print a, b

As explained here, you can use:

function replaceall(str,replace,with_this)
{
    var str_hasil ="";
    var temp;

    for(var i=0;i<str.length;i++) // not need to be equal. it causes the last change: undefined..
    {
        if (str[i] == replace)
        {
            temp = with_this;
        }
        else
        {
                temp = str[i];
        }

        str_hasil += temp;
    }

    return str_hasil;
}

... which you can then call using:

var str = "50.000.000";
alert(replaceall(str,'.',''));

The function will alert "50000000"

Open up a command prompt then type...

netstat -a

The below program will be compatible with Java 9+ version only...

To get the CurrentProcess information,

public class CurrentProcess {
    public static void main(String[] args) {
        ProcessHandle handle = ProcessHandle.current();
        System.out.println("Current Running Process Id: "+handle.pid());
        ProcessHandle.Info info = handle.info();
        System.out.println("ProcessHandle.Info : "+info);
    }
}

For all running processes,

import java.util.List;
import java.util.stream.Collectors;

public class AllProcesses {
    public static void main(String[] args) {
        ProcessHandle.allProcesses().forEach(processHandle -> {
            System.out.println(processHandle.pid()+" "+processHandle.info());
        });
    }
}

The arrange function in the plyr package makes it easy to sort by multiple columns. For example, to sort DF by ID first and then decreasing by num, you can write

plyr::arrange(DF, ID, desc(num))

I got the same error, but when i did as below, it resolved the issue.
Instead of writing like this:

List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1);

use the below one:

ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1);

Try this:

if (value instanceof Array) {
alert('value is Array!');
} else {
alert('Not an array');
}

According to Microsoft docs:

the read-first approach requires an extra database read, and can result in more complex code for handling concurrency conflict

However, you should know that using Update method on DbContext will mark all the fields as modified and will include all of them in the query. If you want to update a subset of fields you should use the Attach method and then mark the desired field as modified manually.

context.Attach(person);
context.Entry(person).Property(p => p.Name).IsModified = true;
context.SaveChanges();

They often forget that iterator must convert to const_iterator but not the other way around. Here is a way to do that:

template<class T, class Tag = void>
class IntrusiveSlistIterator
   : public std::iterator<std::forward_iterator_tag, T>
{
    typedef SlistNode<Tag> Node;
    Node* node_;

public:
    IntrusiveSlistIterator(Node* node);

    T& operator*() const;
    T* operator->() const;

    IntrusiveSlistIterator& operator++();
    IntrusiveSlistIterator operator++(int);

    friend bool operator==(IntrusiveSlistIterator a, IntrusiveSlistIterator b);
    friend bool operator!=(IntrusiveSlistIterator a, IntrusiveSlistIterator b);

    // one way conversion: iterator -> const_iterator
    operator IntrusiveSlistIterator<T const, Tag>() const;
};

In the above notice how IntrusiveSlistIterator<T> converts to IntrusiveSlistIterator<T const>. If T is already const this conversion never gets used.

As an alternate streaming approach:

• dump each col into a file
• use python or unix paste command to rejoin on tab, csv, whatever.

Both steps should handle steaming just fine.

Pitfalls:

• if you have 1000s of columns, you might run into the unix file handle limit!

This is a bit circuitous because touch doesn't take a raw time_t value, but it should do the job pretty safely in a script. (The -r option to date is present in MacOS X; I've not double-checked GNU.) The 'time' variable could be avoided by writing the command substitution directly in the touch command line.

time=$(date -r 1312603983 '+%Y%m%d%H%M.%S')
marker=/tmp/marker.$$
trap "rm -f $marker; exit 1" 0 1 2 3 13 15
touch -t $time $marker
find . -type f -newer $marker
rm -f $marker
trap 0

Here's a quick code snippet that will find the first non-empty line in a string:

string line1;
while (
    ((line1 = sr.ReadLine()) != null) &&
    ((line1 = line1.Trim()).Length == 0)
)
{ /* Do nothing - just trying to find first non-empty line*/ }

if(line1 == null){ /* Error - no non-empty lines in string */ }

More generally.

byte[] buf = new byte[] { 123, 2, 233 };

string s = String.Concat(buf.Select(b => b.ToString("X2")));

HTTP 2.0 is a binary protocol that multiplexes numerous streams going over a single (normally TLS-encrypted) TCP connection.

The contents of each stream are HTTP 1.1 requests and responses, just encoded and packed up differently. HTTP2 adds a number of features to manage the streams, but leaves old semantics untouched.

I know this is an old question, but I was looking to do the same thing and have found what I think is a simpler solution. It appears that cout has this function built in with cout.fill(), see the link for a 'full' explanation

http://www.java-samples.com/showtutorial.php?tutorialid=458

cout.width(11);
cout.fill('.');
cout << "lolcat" << endl;

outputs

.....lolcat

Not sure what you meant with "Can I increase the size of this variable without worrying about the SQL limit?". As long you do not try to insert a more than 4000 VARCHAR2 into a VARCHAR2 SQL column there is nothing to worry about.

Here is the exact reference (this is 11g but true also for 10g)

http://docs.oracle.com/cd/E11882_01/appdev.112/e17126/datatypes.htm

VARCHAR2 Maximum Size in PL/SQL: 32,767 bytes Maximum Size in SQL 4,000 bytes

First you need to define a LocationListener to handle location changes.

private final LocationListener mLocationListener = new LocationListener() {
    @Override
    public void onLocationChanged(final Location location) {
        //your code here
    }
};

Then get the LocationManager and ask for location updates

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    mLocationManager = (LocationManager) getSystemService(LOCATION_SERVICE);

    mLocationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, LOCATION_REFRESH_TIME,
            LOCATION_REFRESH_DISTANCE, mLocationListener);
}

And finally make sure that you have added the permission on the Manifest,

For using only network based location use this one

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>

For GPS based location, this one

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>

As of PowerShell 5.1 there cmdlet New-LocalUser which could create local user account.

Example of usage:

Create a user account

New-LocalUser -Name "User02" -Description "Description of this account." -NoPassword

or Create a user account that has a password

$Password = Read-Host -AsSecureString
New-LocalUser "User03" -Password $Password -FullName "Third User" -Description "Description of this account."

or Create a user account that is connected to a Microsoft account

New-LocalUser -Name "MicrosoftAccount\usr [email protected]" -Description "Description of this account." 

I faced the same error.

I solved the problem by deleting all the contents of bin folders of all the dependent projects/libraries.

This error mainly happens due to version changes.

On *nix, you can also run a headless X Window server like Xvfb and point the DISPLAY environment variable to it:

Fake X server for testing?

use ONLY

function init() { 
    about = document.getElementById("about");
    about.style.color = 'blue';
}

.innerHTML() sets or gets the HTML syntax describing the element's descendants., All you need is an object here.

Demo

I use the timestamp

i.e

new File( simpleDateFormat.format( new Date() ) );

And have the simpleDateFormat initialized to something like as:

new SimpleDateFormat("File-ddMMyy-hhmmss.SSS.txt");

EDIT

What about

new File(String.format("%s.%s", sdf.format( new Date() ),
                                random.nextInt(9)));

Unless the number of files created in the same second is too high.

If that's the case and the name doesn't matters

 new File( "file."+count++ );

:P

For the URI query use urlencode/urldecode; for anything else use rawurlencode/rawurldecode.

The difference between urlencode and rawurlencode is that

• urlencode encodes according to application/x-www-form-urlencoded (space is encoded with +) while
• rawurlencode encodes according to the plain Percent-Encoding (space is encoded with %20).

"mondate" is somewhat similar to "Date" except that adding n adds n months rather than n days:

> library(mondate)
> d <- as.Date("2004-01-31")
> as.mondate(d) + 1
mondate: timeunits="months"
[1] 2004-02-29

You have 3 options to edit commits in Mercurial:

1. hg strip --keep --rev -1 undo the last (1) commit(s), so you can do it again (see this answer for more information).

2. Using the MQ extension, which is shipped with Mercurial

3. Even if it isn't shipped with Mercurial, the Histedit extension is worth mentioning

You can also have a look on the Editing History page of the Mercurial wiki.

In short, editing history is really hard and discouraged. And if you've already pushed your changes, there's barely nothing you can do, except if you have total control of all the other clones.

I'm not really familiar with the git commit --amend command, but AFAIK, Histedit is what seems to be the closest approach, but sadly it isn't shipped with Mercurial. MQ is really complicated to use, but you can do nearly anything with it.

Anybody coming from Manjaro/Arch, installing XAMPP with PHP8 and then downgrading to 7.4 will get this error. To fix, simply go to /opt/lampp/var/mysql/ with Thunar as root user, and delete the database file with the same database name in question and database should be gone. You can get the database name with PhpMyAdmin.

Set the class .fill to height: 100%

.fill { 
    min-height: 100%;
    height: 100%;
}

JSFiddle

(I put a red background for #map so you can see it takes up 100% height)

This error means you can not directly load data from file system because there are security issues behind this. The only solution that I know is create a web service to serve load files.

As Ben said, you'll need to work with the UIView's layer, using a CATransform3D to perform the layer's rotation. The trick to get perspective working, as described here, is to directly access one of the matrix cells of the CATransform3D (m34). Matrix math has never been my thing, so I can't explain exactly why this works, but it does. You'll need to set this value to a negative fraction for your initial transform, then apply your layer rotation transforms to that. You should also be able to do the following:

Objective-C

UIView *myView = [[self subviews] objectAtIndex:0];
CALayer *layer = myView.layer;
CATransform3D rotationAndPerspectiveTransform = CATransform3DIdentity;
rotationAndPerspectiveTransform.m34 = 1.0 / -500;
rotationAndPerspectiveTransform = CATransform3DRotate(rotationAndPerspectiveTransform, 45.0f * M_PI / 180.0f, 0.0f, 1.0f, 0.0f);
layer.transform = rotationAndPerspectiveTransform;

Swift 5.0

if let myView = self.subviews.first {
    let layer = myView.layer
    var rotationAndPerspectiveTransform = CATransform3DIdentity
    rotationAndPerspectiveTransform.m34 = 1.0 / -500
    rotationAndPerspectiveTransform = CATransform3DRotate(rotationAndPerspectiveTransform, 45.0 * .pi / 180.0, 0.0, 1.0, 0.0)
    layer.transform = rotationAndPerspectiveTransform
}

which rebuilds the layer transform from scratch for each rotation.

A full example of this (with code) can be found here, where I've implemented touch-based rotation and scaling on a couple of CALayers, based on an example by Bill Dudney. The newest version of the program, at the very bottom of the page, implements this kind of perspective operation. The code should be reasonably simple to read.

The sublayerTransform you refer to in your response is a transform that is applied to the sublayers of your UIView's CALayer. If you don't have any sublayers, don't worry about it. I use the sublayerTransform in my example simply because there are two CALayers contained within the one layer that I'm rotating.

Great reference. Thanks! An addition to it:

If you happen to have a library project included which has declared custom attributes for a custom view, you have to declare your project namespace, not the library one's. Eg:

Given that the library has the package "com.example.library.customview" and the working project has the package "com.example.customview", then:

Will not work (shows the error " error: No resource identifier found for attribute 'newAttr' in package 'com.example.library.customview'" ):

<com.library.CustomView
        xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res/com.example.library.customview"
        android:id="@+id/myView"
        app:newAttr="value" />

Will work:

<com.library.CustomView
        xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res/com.example.customview"
        android:id="@+id/myView"
        app:newAttr="value" />

Here's a simpler solution: install python-chromedrive package, import it in your script, and it's done.

Step by step:
1. pip install chromedriver-binary
2. import the package

from selenium import webdriver
import chromedriver_binary  # Adds chromedriver binary to path

driver = webdriver.Chrome()
driver.get("http://www.python.org")

You are looking for the DateTime.Parse() method (MSDN Article)

So you can do:

var dateTime = DateTime.Parse("01/01/2001");

Which will give you a DateTime typed object.

If you need to specify which date format you want to use, you would use DateTime.ParseExact (MSDN Article)

Which you would use in a situation like this (Where you are using a British style date format):

string[] formats= { "dd/MM/yyyy" }
var dateTime = DateTime.ParseExact("01/01/2001", formats, new CultureInfo("en-US"), DateTimeStyles.None);

These specific lines are the usual wrapper for jQuery plugins:

"...to make sure that your plugin doesn't collide with other libraries that might use the dollar sign, it's a best practice to pass jQuery to a self executing function (closure) that maps it to the dollar sign so it can't be overwritten by another library in the scope of its execution."

(function( $ ){
  $.fn.myPlugin = function() {
    // Do your awesome plugin stuff here
  };
})( jQuery );

From http://docs.jquery.com/Plugins/Authoring

By setting the CSS max-width property to 100%, an image will fill the width of it's parenting element, but won’t render larger than it's actual size, thus preserving resolution.

Setting the height property to auto maintains the aspect ratio of the image, using this technique allows static height to be overridden and enables the image to flex proportionally in all directions.

img {
    max-width: 100%;
    height: auto;      
}

In spring pre-3.0 it doesn't matter which one.

In spring 3.0 there's support for the standard (JSR-330) annotation @javax.inject.Inject - use it, with a combination of @Qualifier. Note that spring now also supports the @javax.inject.Qualifier meta-annotation:

@Qualifier
@Retention(RUNTIME)
public @interface YourQualifier {}

So you can have

<bean class="com.pkg.SomeBean">
   <qualifier type="YourQualifier"/>
</bean>

or

@YourQualifier
@Component
public class SomeBean implements Foo { .. }

And then:

@Inject @YourQualifier private Foo foo;

This makes less use of String-names, which can be misspelled and are harder to maintain.

As for the original question: both, without specifying any attributes of the annotation, perform injection by type. The difference is:

• @Resource allows you to specify a name of the injected bean
• @Autowired allows you to mark it as non-mandatory.

This is a comprehensive answer to this question. I have done this because this page is high on the Google search results and the answer does not go into enough detail. This post assumes that you are competent at using Visual Studio C# forms. This is based on VS2012.

1. Start by simply dragging a ContextMenuStrip onto the form. It will just put it into the top left corner where you can add your menu items and rename it as you see fit.

2. You will have to view code and enter in an event yourself on the form. Create a mouse down event for the item in question and then assign a right click event for it like so (I have called the ContextMenuStrip "rightClickMenuStrip"):

   private void pictureBox1_MouseDown(object sender, MouseEventArgs e)
   {
   switch (e.Button)
       {
           case MouseButtons.Right:
           {
               rightClickMenuStrip.Show(this, new Point(e.X, e.Y));//places the menu at the pointer position
           }
           break;
       }
   }
   

3. Assign the event handler manually to the form.designer (you may need to add a "using" for System.Windows.Forms; You can just resolve it):

   this.pictureBox1.MouseDown += new MouseEventHandler(this.pictureBox1_MouseDown);
   

4. All that is needed at this point is to simply double click each menu item and do the desired operations for each click event in the same way you would for any other button.

This is the basic code for this operation. You can obviously modify it to fit in with your coding practices.

If you still get the exception in the server startup after changing listen port, you should try changing Pointbase server port and debug port in setDomainEnv.cmd

I solved this problem by doing the "subselect" like it:

string newQuery = "select * from (" + query + ") as temp";

When do it on mysql, all collunms properties (unique, non-null ...) will be cleared.

select top 3 * from emp  order by sal desc

You can still use EditorFor. Just pass the style/whichever html attribute as ViewData.

@Html.EditorFor(model => model.YourProperty, new { style = "Width:50px" })

Because EditorFor uses templates to render, you could override the default template for your property and simply pass the style attribute as ViewData.

So your EditorTemplate would like the following:

@inherits System.Web.Mvc.WebViewPage<object>

@Html.TextBoxFor(m => m, new { @class = "text ui-widget-content", style=ViewData["style"] })

In addition to CAST and CONVERT, if you are using Sql Server 2008, you can convert to a date type (or use that type to start with), and then optionally convert again to a varchar:

declare @myDate date
set @myDate = getdate()
print cast(@myDate as varchar(10))

output:

I had the same problem on OSX OpenSSL 1.0.1i from Macports, and also had to specify CApath as a workaround (and as mentioned in the Ubuntu bug report, even an invalid CApath will make openssl look in the default directory). Interestingly, connecting to the same server using PHP's openssl functions (as used in PHPMailer 5) worked fine.

For me none of the suggested methods worked - using cert, HTTP, trusted-host.

In my case switching to a different version of the package worked (paho-mqtt 1.3.1 instead of paho-mqtt 1.3.0 in this instance).

Looks like problem was specific to that package version.

What is it?

When you create an object in a .Net framework application, you don't need to think about how the data is stored in memory. Because the .Net Framework takes care of that for you. However, if you want to store the contents of an object to a file, send an object to another process or transmit it across the network, you do have to think about how the object is represented because you will need to convert to a different format. This conversion is called SERIALIZATION.

Uses for Serialization

Serialization allows the developer to save the state of an object and recreate it as needed, providing storage of objects as well as data exchange. Through serialization, a developer can perform actions like sending the object to a remote application by means of a Web Service, passing an object from one domain to another, passing an object through a firewall as an XML string, or maintaining security or user-specific information across applications.

Apply SerializableAttribute to a type to indicate that instances of this type can be serialized. Apply the SerializableAttribute even if the class also implements the ISerializable interface to control the serialization process.

All the public and private fields in a type that are marked by the SerializableAttribute are serialized by default, unless the type implements the ISerializable interface to override the serialization process. The default serialization process excludes fields that are marked with NonSerializedAttribute. If a field of a serializable type contains a pointer, a handle, or some other data structure that is specific to a particular environment, and cannot be meaningfully reconstituted in a different environment, then you might want to apply NonSerializedAttribute to that field.

See MSDN for more details.

Edit 1

Any reason to not mark something as serializable

When transferring or saving data, you need to send or save only the required data. So there will be less transfer delays and storage issues. So you can opt out unnecessary chunk of data when serializing.

The solution below uses a double loop to add data to the bottom of a 2x2 array in the Case 3. The inner loop pushes selected elements' values into a new row array. The outerloop then pushes the new row array to the bottom of an existing array (see Newbie: Add values to two-dimensional array with for loops, Google Apps Script).

In this example, I created a function that extracts a section from an existing array. The extracted section can be a row (full or partial), a column (full or partial), or a 2x2 section of the existing array. A new blank array (newArr) is filled by pushing the relevant section from the existing array (arr) into the new array.

 function arraySection(arr, r1, c1, rLength, cLength) {      
   rowMax = arr.length;
    if(isNaN(rowMax)){rowMax = 1};
   colMax = arr[0].length;
   if(isNaN(colMax)){colMax = 1};
   var r2 = r1 + rLength - 1;
   var c2 = c1 + cLength - 1;

   if ((r1< 0 || r1 > r2 || r1 > rowMax || (r1 | 0) != r1) || (r2 < 0 || 
     r2 > rowMax || (r2 | 0) != r2)|| (c1< 0 || c1 > c2 || c1 > colMax || 
   (c1 | 0) != c1) ||(c2 < 0 || c2 > colMax || (c2 | 0) != c2)){
        throw new Error(
        'arraySection: invalid input')       
        return;
     };
   var newArr = [];

// Case 1: extracted section is a column array,

re.match attempts to match a pattern at the beginning of the string. re.search attempts to match the pattern throughout the string until it finds a match.

Is this role attribute necessary?

Answer: Yes.

• The role attribute is necessary to support Accessible Rich Internet Applications (WAI-ARIA) to define roles in XML-based languages, when the languages do not define their own role attribute.
• Although this is the reason the role attribute is published by the Protocols and Formats Working Group, the attribute has more general use cases as well.

It provides you:

• Accessibility
• Device adaptation
• Server-side processing
• Complex data description,...etc.

I found the above when looking for downloading from FTP with username and address in URL. Users supply information and then make the calls.

This was helpful because our organization has Kaspersky AV which blocks active FTP.exe, but not web connections. We were unable to develop in house with ftp.exe and this was our solution. Hope this helps other looking for info!

http://licenseplate.sourceforge.net Python (I have not tested it)

To remove the license key:

1. Find the IntelliJ configuration directory
2. Find the .key license file
3. Remove or rename the .key license file

In my case on a Windows 7 machine I could find this license key in C:\Users\you\.IntelliJIdea13\config\idea13.key

The reason why your full-width-div doesn't stretch 100% to your screen it's because of its parent "container" which occupies only about 80% of the screen.

If you want to make it stretch 100% to the screen either you make the "full-width-div" position fixed or use the "container-fluid" class instead of "container".

I guess this should be quick and can be used with a Python API:

git branch --contains HEAD
* master

You are missing PIL (Python Image Library and Imaging package). To install PIL I used

 pip install pillow

For my machine running Mac OSX 10.6.8, I downloaded Imaging package and installed it from source. http://effbot.org/downloads/Imaging-1.1.6.tar.gz and cd into Download directory. Then run these:

    $ gunzip Imaging-1.1.6.tar.gz
    $ tar xvf Imaging-1.1.6.tar
    $ cd Imaging-1.1.6
    $ python setup.py install

Or if you have PIP installed in your Mac

 pip install http://effbot.org/downloads/Imaging-1.1.6.tar.gz

then you can use:

from PIL import Image

in your python code.

try this code

cd /go/to/path
git pull origin master

You'd have to set up the post-build shell script as a separate Jenkins job and trigger it as a post-build step. It looks like you will need to use the Parameterized Trigger Plugin as the standard "Build other projects" option only works if your triggering build is successful.

Use the DateTime class instead, as it supports timezones. The DateTime equivalent of date() is DateTime::format.

An extremely helpful wrapper for DateTime is Carbon - definitely give it a look.

You'll want to store in the database as UTC and convert on the application level.

...and when I got one how to process it (do I need to use Fourier Transform like it was instructed in the above post)?

If you want a "tap" then I think you are interested in amplitude more than frequency. So Fourier transforms probably aren't useful for your particular goal. You probably want to make a running measurement of the short-term (say 10 ms) amplitude of the input, and detect when it suddenly increases by a certain delta. You would need to tune the parameters of:

• what is the "short-term" amplitude measurement
• what is the delta increase you look for
• how quickly the delta change must occur

Although I said you're not interested in frequency, you might want to do some filtering first, to filter out especially low and high frequency components. That might help you avoid some "false positives". You could do that with an FIR or IIR digital filter; Fourier isn't necessary.

As @Musa comments it, it seems that the reason is that:

Postman doesn't care about SOP, it's a dev tool not a browser

By the way here's a chrome extension in order to make it work on your browser (this one is for chrome, but you can find either for FF or Safari).

Check here if you want to learn more about Cross-Origin and why it's working for extensions.

Here's another approach based off Stephan Hoyer's solution

getRandomString (length) {
  var chars = 'abcdefghkmnpqrstuvwxyz23456789';
  return times(length, () => sample(chars)).join('');
}

I find that solution more elegant:

for (let val in myEnum ) {

 if ( isNaN( parseInt( val )) )
     console.log( val );
}

It displays:

bar 
foo

This approach will not consume any resources for keeping process alive.

while :; do sleep 1; done & kill -STOP $! && wait $!

Breakdown

• while :; do sleep 1; done & Creates a dummy process in background
• kill -STOP $! Stops the background process
• wait $! Wait for the background process, this will be blocking forever, cause background process was stopped before

The gdi32 library is already installed on your computer, few programs will run without it. Your compiler will (if installed properly) normally come with an import library, which is what the linker uses to make a binding between your program and the file in the system. (In the unlikely case that your compiler does not come with import libraries for the system libs, you will need to download the Microsoft Windows Platform SDK.)

To link with gdi32:

This will reliably work with MinGW-gcc for all system libraries (it should work if you use any other compiler too, but I can't talk about things I've not tried). You can also write the library's full name, but writing libgdi32.a has no advantage over gdi32 other than being more type work.
If it does not work for some reason, you may have to provide a different name (for example the library is named gdi32.lib for MSVC).

For libraries in some odd locations or project subfolders, you will need to provide a proper pathname (click on the "..." button for a file select dialog).

You can use max_element() function to find the position of the max element.

int main()
{
    int num, arr[10];
    int x, y, a, b;

    cin >> num;

    for (int i = 0; i < num; i++)
    {
        cin >> arr[i];
    }

    cout << "Max element Index: " << max_element(arr, arr + num) - arr;

    return 0;
}

Solution :

1 - Install Cygwin and note the directory where it gets installed.

It was C:\cygwin64 in my case. The sh.exe which is needed to run shell scripts is in the "bin" sub-directory, i.e. C:\cygwin64\bin.

2 - Tell Jenkins where sh.exe is located.

Jenkins web console > Manage Jenkins > Configure System > Under shell, set the "Shell executable" = C:\cygwin64\bin\sh.exe > Click apply & also click save.

That's all I did to make my job pass. I was running Jenkins from a war file and I did not need to restart it to make this work.

Please consider long and hard if you can't get around implementing your own cryptography

The ugly truth of the matter is that if you are asking this question you will probably not be able to design and implement a secure system.

Let me illustrate my point: Imagine you are building a web application and you need to store some session data. You could assign each user a session ID and store the session data on the server in a hash map mapping session ID to session data. But then you have to deal with this pesky state on the server and if at some point you need more than one server things will get messy. So instead you have the idea to store the session data in a cookie on the client side. You will encrypt it of course so the user cannot read and manipulate the data. So what mode should you use? Coming here you read the top answer (sorry for singling you out myforwik). The first one covered - ECB - is not for you, you want to encrypt more than one block, the next one - CBC - sounds good and you don't need the parallelism of CTR, you don't need random access, so no XTS and patents are a PITA, so no OCB. Using your crypto library you realize that you need some padding because you can only encrypt multiples of the block size. You choose PKCS7 because it was defined in some serious cryptography standards. After reading somewhere that CBC is provably secure if used with a random IV and a secure block cipher, you rest at ease even though you are storing your sensitive data on the client side.

Years later after your service has indeed grown to significant size, an IT security specialist contacts you in a responsible disclosure. She's telling you that she can decrypt all your cookies using a padding oracle attack, because your code produces an error page if the padding is somehow broken.

This is not a hypothetical scenario: Microsoft had this exact flaw in ASP.NET until a few years ago.

The problem is there are a lot of pitfalls regarding cryptography and it is extremely easy to build a system that looks secure for the layman but is trivial to break for a knowledgeable attacker.

What to do if you need to encrypt data

For live connections use TLS (be sure to check the hostname of the certificate and the issuer chain). If you can't use TLS, look for the highest level API your system has to offer for your task and be sure you understand the guarantees it offers and more important what it does not guarantee. For the example above a framework like Play offers client side storage facilities, it does not invalidate the stored data after some time, though, and if you changed the client side state, an attacker can restore a previous state without you noticing.

If there is no high level abstraction available use a high level crypto library. A prominent example is NaCl and a portable implementation with many language bindings is Sodium. Using such a library you do not have to care about encryption modes etc. but you have to be even more careful about the usage details than with a higher level abstraction, like never using a nonce twice. For custom protocol building (say you want something like TLS, but not over TCP or UDP) there are frameworks like Noise and associated implementations that do most of the heavy lifting for you, but their flexibility also means there is a lot of room for error, if you don't understand in depth what all the components do.

If for some reason you cannot use a high level crypto library, for example because you need to interact with existing system in a specific way, there is no way around educating yourself thoroughly. I recommend reading Cryptography Engineering by Ferguson, Kohno and Schneier. Please don't fool yourself into believing you can build a secure system without the necessary background. Cryptography is extremely subtle and it's nigh impossible to test the security of a system.

Comparison of the modes

Encryption only:

• Modes that require padding: Like in the example, padding can generally be dangerous because it opens up the possibility of padding oracle attacks. The easiest defense is to authenticate every message before decryption. See below.
  • ECB encrypts each block of data independently and the same plaintext block will result in the same ciphertext block. Take a look at the ECB encrypted Tux image on the ECB Wikipedia page to see why this is a serious problem. I don't know of any use case where ECB would be acceptable.
  • CBC has an IV and thus needs randomness every time a message is encrypted, changing a part of the message requires re-encrypting everything after the change, transmission errors in one ciphertext block completely destroy the plaintext and change the decryption of the next block, decryption can be parallelized / encryption can't, the plaintext is malleable to a certain degree - this can be a problem.
• Stream cipher modes: These modes generate a pseudo random stream of data that may or may not depend the plaintext. Similarly to stream ciphers generally, the generated pseudo random stream is XORed with the plaintext to generate the ciphertext. As you can use as many bits of the random stream as you like you don't need padding at all. Disadvantage of this simplicity is that the encryption is completely malleable, meaning that the decryption can be changed by an attacker in any way he likes as for a plaintext p1, a ciphertext c1 and a pseudo random stream r and attacker can choose a difference d such that the decryption of a ciphertext c2=c1?d is p2 = p1?d, as p2 = c2?r = (c1 ? d) ? r = d ? (c1 ? r). Also the same pseudo random stream must never be used twice as for two ciphertexts c1=p1?r and c2=p2?r, an attacker can compute the xor of the two plaintexts as c1?c2=p1?r?p2?r=p1?p2. That also means that changing the message requires complete reencryption, if the original message could have been obtained by an attacker. All of the following steam cipher modes only need the encryption operation of the block cipher, so depending on the cipher this might save some (silicon or machine code) space in extremely constricted environments.
  • CTR is simple, it creates a pseudo random stream that is independent of the plaintext, different pseudo random streams are obtained by counting up from different nonces/IVs which are multiplied by a maximum message length so that overlap is prevented, using nonces message encryption is possible without per message randomness, decryption and encryption are completed parallelizable, transmission errors only effect the wrong bits and nothing more
  • OFB also creates a pseudo random stream independent of the plaintext, different pseudo random streams are obtained by starting with a different nonce or random IV for every message, neither encryption nor decryption is parallelizable, as with CTR using nonces message encryption is possible without per message randomness, as with CTR transmission errors only effect the wrong bits and nothing more
  • CFB's pseudo random stream depends on the plaintext, a different nonce or random IV is needed for every message, like with CTR and OFB using nonces message encryption is possible without per message randomness, decryption is parallelizable / encryption is not, transmission errors completely destroy the following block, but only effect the wrong bits in the current block
• Disk encryption modes: These modes are specialized to encrypt data below the file system abstraction. For efficiency reasons changing some data on the disc must only require the rewrite of at most one disc block (512 bytes or 4kib). They are out of scope of this answer as they have vastly different usage scenarios than the other. Don't use them for anything except block level disc encryption. Some members: XEX, XTS, LRW.

Authenticated encryption:

To prevent padding oracle attacks and changes to the ciphertext, one can compute a message authentication code (MAC) on the ciphertext and only decrypt it if it has not been tampered with. This is called encrypt-then-mac and should be preferred to any other order. Except for very few use cases authenticity is as important as confidentiality (the latter of which is the aim of encryption). Authenticated encryption schemes (with associated data (AEAD)) combine the two part process of encryption and authentication into one block cipher mode that also produces an authentication tag in the process. In most cases this results in speed improvement.

• CCM is a simple combination of CTR mode and a CBC-MAC. Using two block cipher encryptions per block it is very slow.
• OCB is faster but encumbered by patents. For free (as in freedom) or non-military software the patent holder has granted a free license, though.
• GCM is a very fast but arguably complex combination of CTR mode and GHASH, a MAC over the Galois field with 2^128 elements. Its wide use in important network standards like TLS 1.2 is reflected by a special instruction Intel has introduced to speed up the calculation of GHASH.

Recommendation:

Considering the importance of authentication I would recommend the following two block cipher modes for most use cases (except for disk encryption purposes): If the data is authenticated by an asymmetric signature use CBC, otherwise use GCM.

• SQL a language for talking to the database. It lets you select data, mutate and create database objects (like tables, views, etc.), change database settings.
• PL-SQL a procedural programming language (with embedded SQL)
• T-SQL (procedural) extensions for SQL used by SQL Server

The simplest solution if you are just storing two strings is NSUserDefaults, in Swift 3 this class has been renamed to just UserDefaults.

It's best to store your keys somewhere globally so that you can reuse them elsewhere in your code.

struct defaultsKeys {
    static let keyOne = "firstStringKey"
    static let keyTwo = "secondStringKey"
}

Swift 3.0, 4.0 & 5.0

// Setting

let defaults = UserDefaults.standard
defaults.set("Some String Value", forKey: defaultsKeys.keyOne)
defaults.set("Another String Value", forKey: defaultsKeys.keyTwo)

// Getting

let defaults = UserDefaults.standard
if let stringOne = defaults.string(forKey: defaultsKeys.keyOne) {
    print(stringOne) // Some String Value
}
if let stringTwo = defaults.string(forKey: defaultsKeys.keyTwo) {
    print(stringTwo) // Another String Value
}

Swift 2.0

// Setting

let defaults = NSUserDefaults.standardUserDefaults()
defaults.setObject("Some String Value", forKey: defaultsKeys.keyOne)
defaults.setObject("Another String Value", forKey: defaultsKeys.keyTwo)

// Getting

let defaults = NSUserDefaults.standardUserDefaults()
if let stringOne = defaults.stringForKey(defaultsKeys.keyOne) {
    print(stringOne) // Some String Value
}
if let stringTwo = defaults.stringForKey(defaultsKeys.keyTwo) {
    print(stringTwo) // Another String Value
}

For anything more serious than minor config, flags or base strings you should use some sort of persistent store - A popular option at the moment is Realm but you can also use SQLite or Apples very own CoreData.

This is the best way to do it, very simple.

$msg = "Hello this is a string";
$first_index_of_i = stripos($msg,'i');
$last_index_of_i = strripos($msg, 'i');

echo "First i : " . $first_index_of_i . PHP_EOL ."Last i : " . $last_index_of_i;

What are they?

Nothing special. Just as same as common Java Class Instance.

But those class are Synthetic proxy classes created by java.lang.reflect.Proxy#newProxyInstance

What is there relationship to the JVM? Are they JVM implementation specific?

Introduced in 1.3

http://docs.oracle.com/javase/1.3/docs/relnotes/features.html#reflection

It is a part of Java. so each JVM should support it.

How are they created (Openjdk7 source)?

In short : they are created using JVM ASM tech ( defining javabyte code at runtime )

something using same tech:

• asm( http://asm.ow2.org/ )
• cglib( http://cglib.sourceforge.net/ )

What happens after calling java.lang.reflect.Proxy#newProxyInstance

1. reading the source you can see newProxyInstance call getProxyClass0 to obtain a `Class

   `

2. after lots of cache or sth it calls the magic ProxyGenerator.generateProxyClass which return a byte[]
3. call ClassLoader define class to load the generated $Proxy Class (the classname you have seen)
4. just instance it and ready for use

What happens in magic sun.misc.ProxyGenerator

1. draw a class(bytecode) combining all methods in the interfaces into one

2. each method is build with same bytecode like

   1. get calling Method meth info (stored while generating)
   2. pass info into invocation handler's invoke()
   3. get return value from invocation handler's invoke()
   4. just return it

3. the class(bytecode) represent in form of byte[]

How to draw a class

Thinking your java codes are compiled into bytecodes, just do this at runtime

Talk is cheap show you the code

You can subclass JPanel - here is an extract from my ImagePanel, which puts an image in any one of 5 locations, top/left, top/right, middle/middle, bottom/left or bottom/right:

protected void paintComponent(Graphics gc) {
    super.paintComponent(gc);

    Dimension                           cs=getSize();                           // component size

    gc=gc.create();
    gc.clipRect(insets.left,insets.top,(cs.width-insets.left-insets.right),(cs.height-insets.top-insets.bottom));
    if(mmImage!=null) { gc.drawImage(mmImage,(((cs.width-mmSize.width)/2)       +mmHrzShift),(((cs.height-mmSize.height)/2)        +mmVrtShift),null); }
    if(tlImage!=null) { gc.drawImage(tlImage,(insets.left                       +tlHrzShift),(insets.top                           +tlVrtShift),null); }

My problem was solved checking if the process was running on Ubuntu 12.04

ps ax | grep mysql

Then the answer was that it wasn't running, so I did

sudo service mysql start

Or try

sudo /etc/init.d/mysql start

Another alternative to @TouchBoarder's answer above is that you may also have two layout files with the same name but for different api versions. You should delete the older my_file.xml file

my_file.xml
my_file.xml(v21)

This is a method for converting a svg picture to a gif using standard php GD tools

1) You put the image into a canvas element in the browser:

<canvas id=myCanvas></canvas>

<script>
var Key='picturename'
var canvas = document.getElementById('myCanvas');
var context = canvas.getContext('2d');
base_image = new Image();
base_image.src = myimage.svg;
base_image.onload = function(){

    //get the image info as base64 text string

    var dataURL = canvas.toDataURL();
    //Post the image (dataURL) to the server using jQuery post method
    $.post('ProcessPicture.php',{'TheKey':Key,'image': dataURL ,'h': canvas.height,'w':canvas.width,"stemme":stemme } ,function(data,status){ alert(data+' '+status) });
}
</script>    

And then convert it at the server (ProcessPicture.php) from (default) png to gif and save it. (you could have saved as png too then use imagepng instead of image gif):

//receive the posted data in php
$pic=$_POST['image'];
$Key=$_POST['TheKey'];
$height=$_POST['h'];
$width=$_POST['w'];
$dir='../gif/'
$gifName=$dir.$Key.'.gif';
 $pngName=$dir.$Key.'.png';

//split the generated base64 string before the comma. to remove the 'data:image/png;base64, header  created by and get the image data
$data = explode(',', $pic);
$base64img = base64_decode($data[1]);
$dimg=imagecreatefromstring($base64img); 

//in order to avoid copying a black figure into a (default) black background you must create a white background

$im_out = ImageCreateTrueColor($width,$height);
$bgfill = imagecolorallocate( $im_out, 255, 255, 255 );
imagefill( $im_out, 0,0, $bgfill );

//Copy the uploaded picture in on the white background
ImageCopyResampled($im_out, $dimg ,0, 0, 0, 0, $width, $height,$width, $height);

//Make the gif and png file 
imagegif($im_out, $gifName);
imagepng($im_out, $pngName);

The problem with systemPath is that the dependencies' jars won't get distributed along your artifacts as transitive dependencies. Try what I've posted here: Is it best to Mavenize your project jar files or put them in WEB-INF/lib?

Then declare dependencies as usual.

And please read the footer note.

In jQuery, the $ sign is just an alias to jQuery(), then an alias to a function.

This page reports:

Basic syntax is: $(selector).action()

• A dollar sign to define jQuery
• A (selector) to "query (or find)" HTML elements
• A jQuery action() to be performed on the element(s)

This works (pandas v'0.19.2'):

Check to see if the key-value pair is actually showing up in the request:

In Chrome, found somewhere like: F12: Developer Tools > Network Tab > Whatever request you have sent > "view source" under Response Headers

Depending on your testing workflow, if whatever pair you added isn't there, you may just need to clear your browser cache. To verify that your browser is using your most up-to-date code, you can check the page's sources, in Chrome this is found somewhere like: F12: Developer Tools > Sources Tab > YourJavascriptSrc.js and check your code.

But as other answers have said:

xhttp.setRequestHeader(key, value);

should add a key-value pair to your request header, just make sure to place it after your open() and before your send()

I think this example is self explanatory. It runs the method of first parameter, whose name is given in the second parameter.

class MyClass:
   def __init__(self):
      pass
   def MyMethod(self):
      print("Method ran")

# Create an object
object = MyClass()
# Get all the methods of a class
method_list = [func for func in dir(MyClass) if callable(getattr(MyClass, func))]
# You can use any of the methods in method_list
# "MyMethod" is the one we want to use right now

# This is the same as running "object.MyMethod()"
getattr(object,'MyMethod')()

I'm guessing you are more interested in getting some insight into "why" the cosine similarity works (why it provides a good indication of similarity), rather than "how" it is calculated (the specific operations used for the calculation). If your interest is in the latter, see the reference indicated by Daniel in this post, as well as a related SO Question.

To explain both the how and even more so the why, it is useful, at first, to simplify the problem and to work only in two dimensions. Once you get this in 2D, it is easier to think of it in three dimensions, and of course harder to imagine in many more dimensions, but by then we can use linear algebra to do the numeric calculations and also to help us think in terms of lines / vectors / "planes" / "spheres" in n dimensions, even though we can't draw these.

So, in two dimensions: with regards to text similarity this means that we would focus on two distinct terms, say the words "London" and "Paris", and we'd count how many times each of these words is found in each of the two documents we wish to compare. This gives us, for each document, a point in the the x-y plane. For example, if Doc1 had Paris once, and London four times, a point at (1,4) would present this document (with regards to this diminutive evaluation of documents). Or, speaking in terms of vectors, this Doc1 document would be an arrow going from the origin to point (1,4). With this image in mind, let's think about what it means for two documents to be similar and how this relates to the vectors.

VERY similar documents (again with regards to this limited set of dimensions) would have the very same number of references to Paris, AND the very same number of references to London, or maybe, they could have the same ratio of these references. A Document, Doc2, with 2 refs to Paris and 8 refs to London, would also be very similar, only with maybe a longer text or somehow more repetitive of the cities' names, but in the same proportion. Maybe both documents are guides about London, only making passing references to Paris (and how uncool that city is ;-) Just kidding!!!.

Now, less similar documents may also include references to both cities, but in different proportions. Maybe Doc2 would only cite Paris once and London seven times.

Back to our x-y plane, if we draw these hypothetical documents, we see that when they are VERY similar, their vectors overlap (though some vectors may be longer), and as they start to have less in common, these vectors start to diverge, to have a wider angle between them.

By measuring the angle between the vectors, we can get a good idea of their similarity, and to make things even easier, by taking the Cosine of this angle, we have a nice 0 to 1 or -1 to 1 value that is indicative of this similarity, depending on what and how we account for. The smaller the angle, the bigger (closer to 1) the cosine value, and also the higher the similarity.

At the extreme, if Doc1 only cites Paris and Doc2 only cites London, the documents have absolutely nothing in common. Doc1 would have its vector on the x-axis, Doc2 on the y-axis, the angle 90 degrees, Cosine 0. In this case we'd say that these documents are orthogonal to one another.

Adding dimensions:
With this intuitive feel for similarity expressed as a small angle (or large cosine), we can now imagine things in 3 dimensions, say by bringing the word "Amsterdam" into the mix, and visualize quite well how a document with two references to each would have a vector going in a particular direction, and we can see how this direction would compare to a document citing Paris and London three times each, but not Amsterdam, etc. As said, we can try and imagine the this fancy space for 10 or 100 cities. It's hard to draw, but easy to conceptualize.

I'll wrap up just by saying a few words about the formula itself. As I've said, other references provide good information about the calculations.

First in two dimensions. The formula for the Cosine of the angle between two vectors is derived from the trigonometric difference (between angle a and angle b):

cos(a - b) = (cos(a) * cos(b)) + (sin (a) * sin(b))

This formula looks very similar to the dot product formula:

Vect1 . Vect2 =  (x1 * x2) + (y1 * y2)

where cos(a) corresponds to the x value and sin(a) the y value, for the first vector, etc. The only problem, is that x, y, etc. are not exactly the cos and sin values, for these values need to be read on the unit circle. That's where the denominator of the formula kicks in: by dividing by the product of the length of these vectors, the x and y coordinates become normalized.

You could try this:

deptSelected(selected: { id: string; text: string }) {
  console.log(selected) // Shows proper selection!

  // This is how I am trying to set the value
  this.form.controls['dept'].updateValue(selected.id);
}

For more details, you could have a look at the corresponding JS Doc regarding the second parameter of the updateValue method: https://github.com/angular/angular/blob/master/modules/angular2/src/common/forms/model.ts#L269.

Agile is a general philosophy regarding software production, Scrum is an implementation of that philosophy pertaining specifically to project management.

If you look in your installation's bin directory you will see catalina.sh or .bat scripts. If you look in these you will see that they run a setenv.sh or setenv.bat script respectively, if it exists, to set environment variables. The relevant environment variables are described in the comments at the top of catalina.sh/bat. To use them create, for example, a file $CATALINA_HOME/bin/setenv.sh with contents

export JAVA_OPTS="-server -Xmx512m"

For Windows you will need, in setenv.bat, something like

set JAVA_OPTS=-server -Xmx768m

Original answer here

After you run startup.bat, you can easily confirm the correct settings have been applied provided you have turned @echo on somewhere in your catatlina.bat file (a good place could be immediately after echo Using CLASSPATH: "%CLASSPATH%"):

The thing of it is there are 2 main protocol versions of WebSockets in use today. The old version which uses the [0x00][message][0xFF] protocol, and then there's the new version using Hybi formatted packets.

The old protocol version is used by Opera and iPod/iPad/iPhones so it's actually important that backward compatibility is implemented in WebSockets servers. With these browsers using the old protocol, I discovered that refreshing the page, or navigating away from the page, or closing the browser, all result in the browser automatically closing the connection. Great!!

However with browsers using the new protocol version (eg. Firefox, Chrome and eventually IE10), only closing the browser will result in the browser automatically closing the connection. That is to say, if you refresh the page, or navigate away from the page, the browser does NOT automatically close the connection. However, what the browser does do, is send a hybi packet to the server with the first byte (the proto ident) being 0x88 (better known as the close data frame). Once the server receives this packet it can forcefully close the connection itself, if you so choose.

Here's what works directly with Vue custom components.

$('select').on('select2:open', function (e) {
  var OptionsSize = $(this).find("option").size(); // The amount of options 
  var HeightPerOption = 36; // the height in pixels every option should be
  var DropDownHeight = OptionsSize * HeightPerOption;
  $(".select2-results__options").height(DropDownHeight);
});

Make sure to unset the (default) max-height in css:

.select2-container--default .select2-results>.select2-results__options {
  max-height: inherit;
}

(only tested in version 4 of select2)

If you want to keep the GNU compiler extensions, use -std=gnu++0x rather than -std=c++0x. Here's a quote from the man page:

The compiler can accept several base standards, such as c89 or c++98, and GNU dialects of those standards, such as gnu89 or gnu++98. By specifying a base standard, the compiler will accept all programs following that standard and those using GNU extensions that do not contradict it. For example, -std=c89 turns off certain features of GCC that are incompatible with ISO C90, such as the "asm" and "typeof" keywords, but not other GNU extensions that do not have a meaning in ISO C90, such as omitting the middle term of a "?:" expression. On the other hand, by specifying a GNU dialect of a standard, all features the compiler support are enabled, even when those features change the meaning of the base standard and some strict-conforming programs may be rejected. The particular standard is used by -pedantic to identify which features are GNU extensions given that version of the standard. For example-std=gnu89 -pedantic would warn about C++ style // comments, while -std=gnu99 -pedantic would not.

Well, for just getting the filename of your batch the easiest way would be to just use %~n0.

@echo %~n0

will output the name (without the extension) of the currently running batch file (unless executed in a subroutine called by call). The complete list of such “special” substitutions for path names can be found with help for, at the very end of the help:

In addition, substitution of FOR variable references has been enhanced. You can now use the following optional syntax:

%~I         - expands %I removing any surrounding quotes (")
%~fI        - expands %I to a fully qualified path name
%~dI        - expands %I to a drive letter only
%~pI        - expands %I to a path only
%~nI        - expands %I to a file name only
%~xI        - expands %I to a file extension only
%~sI        - expanded path contains short names only
%~aI        - expands %I to file attributes of file
%~tI        - expands %I to date/time of file
%~zI        - expands %I to size of file
%~$PATH:I   - searches the directories listed in the PATH
               environment variable and expands %I to the
               fully qualified name of the first one found.
               If the environment variable name is not
               defined or the file is not found by the
               search, then this modifier expands to the
               empty string

The modifiers can be combined to get compound results:

%~dpI       - expands %I to a drive letter and path only
%~nxI       - expands %I to a file name and extension only
%~fsI       - expands %I to a full path name with short names only

To precisely answer your question, however: Substrings are done using the :~start,length notation:

%var:~10,5%

will extract 5 characters from position 10 in the environment variable %var%.

NOTE: The index of the strings is zero based, so the first character is at position 0, the second at 1, etc.

To get substrings of argument variables such as %0, %1, etc. you have to assign them to a normal environment variable using set first:

:: Does not work:
@echo %1:~10,5

:: Assign argument to local variable first:
set var=%1
@echo %var:~10,5%

The syntax is even more powerful:

• %var:~-7% extracts the last 7 characters from %var%
• %var:~0,-4% would extract all characters except the last four which would also rid you of the file extension (assuming three characters after the period [.]).

See help set for details on that syntax.

You can also do it the following way:

<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script>
 $(document).ready(function(){
     $("#hide").click(function(){
     $("#test").hide();
     });
     $("#show").click(function(){
     $("#test").show();
     });
 });
</script>
</head>

<body>
<h2>This is a test of jQuery!</h2>
<p id="test">This is a hidden paragraph.</p>
<button id="hide">Click me to hide</button>
<button id="show">Click me to show</button>
</body>

the previous answers showed using multiple named functions inside a single .ready block, or a single unnamed function in the .ready block, with another named function outside the .ready block. I found this question while researching if there was a way to have multiple unnamed functions inside the .ready block - I could not get the syntax correct. I finally figured it out, and hoped that by posting my test code I would help others looking for the answer to the same question I had

There's another alternative for lazy people. You can set the layer.cornerRadius key path for your view in the Interface Builder. For example, if your view has a width = height of 48, set layer.cornerRadius = 24:

However, this only works if you have a static size of the view (width/height is fixed) and it's not showing the circle in the interface builder.

I use this:

 public String SEG2HOR( long lnValue) {     //OK
        String lcStr = "00:00:00";
        String lcSign = (lnValue>=0 ? " " : "-");
        lnValue = lnValue * (lnValue>=0 ? 1 : -1); 

        if (lnValue>0) {                
            long lnHor  = (lnValue/3600);
            long lnHor1 = (lnValue % 3600);
            long lnMin  = (lnHor1/60);
            long lnSec  = (lnHor1 % 60);            

                        lcStr = lcSign + ( lnHor < 10 ? "0": "") + String.valueOf(lnHor) +":"+
                              ( lnMin < 10 ? "0": "") + String.valueOf(lnMin) +":"+
                              ( lnSec < 10 ? "0": "") + String.valueOf(lnSec) ;
        }

        return lcStr;           
    }

Your method showFile() declares that it can throw an IOException. Since this is a checked exception, any call to showFile() method must handle the exception somehow. One option is to wrap the call to showFile() in a try-catch block.

 try {
     showFile();
 }
 catch(IOException e) {
    // Code to handle an IOException here
 }

To expand on Ryan's answer, when you are declaring variables (using Dim) you can cheat a little bit by using the predictive text feature in the VBE, as in the image below.

If it shows up in that list, then you can assign an object of that type to a variable. So not just a Worksheet, as Ryan pointed out, but also a Chart, Range, Workbook, Series and on and on.

You set that variable equal to the object you want to manipulate and then you can call methods, pass it to functions, etc, just like Ryan pointed out for this example. You might run into a couple snags when it comes to collections vs objects (Chart or Charts, Range or Ranges, etc) but with trial and error you'll get it for sure.

Just do:

$text = str_replace(' ', '_', $text)

Enclose <img> in <a> tag.

<a href="http://www.google.com.pk"><img src="smiley.gif"></a>

it will open link on same tab, and if you want to open link on new tab then use target="_blank"

<a href="http://www.google.com.pk" target="_blank"><img src="smiley.gif"></a>

IIS_IUSRS group has prominence only if you are using ApplicationPool Identity. Even though you have this group looks empty at run time IIS adds to this group to run a worker process according to microsoft literature.

You can use Hudson Groovy builder to do this.

There is one alternate solution (NOT the best solution) for this problem, but works. Using flag you can handle it, like below

/**
 * Flag to avoid "java.lang.IllegalStateException: Can not perform this action after
 * onSaveInstanceState". Avoid Fragment transaction until onRestoreInstanceState or onResume
 * gets called.
 */
private boolean isOnSaveInstanceStateCalled = false;


@Override
public void onRestoreInstanceState(final Bundle bundle) {
    .....
    isOnSaveInstanceStateCalled = false;
    .....
}

@Override
public void onSaveInstanceState(final Bundle outState) {
    .....
    isOnSaveInstanceStateCalled = true;
    .....
}

@Override
public void onResume() {
    super.onResume();
    isOnSaveInstanceStateCalled = false;
    .....
}

And you can check this boolean value while doing fragment transaction.

private void fragmentReplace(Fragment fragment, String fragmentTag){
    if (!isOnSaveInstanceStateCalled) {
        getSupportFragmentManager()
                .beginTransaction()
                .replace(R.id.layout_container, fragment, fragmentTag)
                .commit();
    }
}

To add something to this (cause I found it while searching on this problem, and my solution involved slightly more)...

If you don't have a "Browse with..." option for .aspx files (as I didn't in a MVC application), the easiest solution is to add a dummy HTML file, and right-click it to set the option as described in the answer. You can remove the file afterward.

The option is actually set in: C:\Documents and Settings[user]\Local Settings\Application Data\Microsoft\VisualStudio[version]\browser.xml

However, if you modify the file directly while VS is running, VS will overwrite it with your previous option on next run. Also, if you edit the default in VS you won't have to worry about getting the schema right, so the work-around dummy file is probably the easiest way.

Using Eloquent Model

$user = new Report();        
$user->email= '[email protected]';  
$user->save();
$lastId = $user->id;

Using Query Builder

$lastId = DB::table('reports')->insertGetId(['email' => '[email protected]']);

I'd like to add df.values.tolist(). (as long as you don't mind to get a column of lists rather than tuples)

import pandas as pd
import numpy as np

size = int(1e+07)
df = pd.DataFrame({'a': np.random.rand(size), 'b': np.random.rand(size)}) 

%timeit df.values.tolist()
1.47 s ± 38.9 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)

%timeit list(zip(df.a,df.b))
1.92 s ± 131 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)

Unfortunately, it's not that easy. There are more complicated things behind the scenes in JBoss (most of them ClassLoader related) that will prevent you from HOT-DEPLOYING your application.

For example, you are not going to be able to HOT-DEPLOY if some of your classes signatures change.

So far, using MyEclipse IDE (a paid distribution of Eclipse) is the only thing I found that does hot deploying quite successfully. Not 100% accuracy though. But certainly better than JBoss Tools, Netbeans or any other Eclipse based solution.

I've been looking for free tools to accomplish what you've just described by asking people in StackOverflow if you want to take a look.

For anyone interested in minimum requirements for each type of character, I would suggest making the following extension over Tomalak's accepted answer:

^(?=(.*[0-9]){%d,})(?=(.*[a-z]){%d,})(?=(.*[A-Z]){%d,})(?=(.*[^0-9a-zA-Z]){%d,})(?=\S+$).{%d,}$

Notice that this is a formatting string and not the final regex pattern. Just substitute %d with the minimum required occurrences for: digits, lowercase, uppercase, non-digit/character, and entire password (respectively). Maximum occurrences are unlikely (unless you want a max of 0, effectively rejecting any such characters) but those could be easily added as well. Notice the extra grouping around each type so that the min/max constraints allow for non-consecutive matches. This worked wonders for a system where we could centrally configure how many of each type of character we required and then have the website as well as two different mobile platforms fetch that information in order to construct the regex pattern based on the above formatting string.

    UIStoryboard* storyboard = [UIStoryboard storyboardWithName:@"storyBoardName" bundle:nil];
    MemberDetailsViewController* controller = [storyboard instantiateViewControllerWithIdentifier:@"viewControllerIdentiferInStoryBoard"];
[self.navigationController pushViewController:viewControllerName animated:YES];

Swift 4:

let storyBoard = UIStoryboard(name: "storyBoardName", bundle:nil)
let memberDetailsViewController = storyBoard.instantiateViewController(withIdentifier: "viewControllerIdentiferInStoryBoard") as! MemberDetailsViewController
self.navigationController?.pushViewController(memberDetailsViewController, animated:true)

Just for completeness' sake (sum is usually preferable), I wanted to mention that we can also use filter to get the truthy values. In the usual case, filter accepts a function as the first argument, but if you pass it None, it will filter for all "truthy" values. This feature is somewhat surprising, but is well documented and works in both Python 2 and 3.

The difference between the versions, is that in Python 2 filter returns a list, so we can use len:

>>> bool_list = [True, True, False, False, False, True]
>>> filter(None, bool_list)
[True, True, True]
>>> len(filter(None, bool_list))
3

But in Python 3, filter returns an iterator, so we can't use len, and if we want to avoid using sum (for any reason) we need to resort to converting the iterator to a list (which makes this much less pretty):

>>> bool_list = [True, True, False, False, False, True]
>>> filter(None, bool_list)
<builtins.filter at 0x7f64feba5710>
>>> list(filter(None, bool_list))
[True, True, True]
>>> len(list(filter(None, bool_list)))
3

I had the same problem and I fixed by setting transparent png image as background for the parent tag.

This is the 1px x 1px PNG Image that I have created with 60% Opacity of black background !

you can also do it with a filter like this:

public class RedirectFilter implements Filter {

public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
    HttpServletRequest req=(HttpServletRequest)request;

    //check if "role" attribute is null
    if(req.getSession().getAttribute("role")==null) {
        //forward request to login.jsp
        req.getRequestDispatcher("/login.jsp").forward(request, response);
    } else {
        chain.doFilter(request, response);
    }
}
}

Visual Studio does elevate itself automatically if the project's application manifest specifies an administrative requestedExecutionLevel, so you just need to edit that. Visual Studio will detect that and relaunch itself as administrator when needed.

After you install the missing zlib dev package you can also use pythonbrew to uninstall and then reinstall the version of python you wanted and it seems like it picks up the new package to compile to correct abilities. This way you can keep using pythonbrew and don't have to do the compilation yourself (though it isn't that difficult)

On Windows, the following steps should re-trigger the GitHub login window when git cloneing:

• Search start menu for "Credential Manager"
• Select "Windows Credentials"
• Delete any credentials related to Git or GitHub

As long as you are using Asp.Net 2.0 or greater, you can also use the library call- System.Web.Security.Membership.GeneratePassword, however it will include special characters.

To get 4 random characters with minimum of 0 special characters-

Membership.GeneratePassword(4, 0)

Usually, the correct way of updating certain fields in one or more model instances is to use the update() method on the respective queryset. Then you do something like this:

affected_surveys = Survey.objects.filter(
    # restrict your queryset by whatever fits you
    # ...
    ).update(active=True)

This way, you don't need to call save() on your model anymore because it gets saved automatically. Also, the update() method returns the number of survey instances that were affected by your update.

$value = 23;
$rounded_value = $value - ($value % 10 - 10);
//$rounded_value is now 30

For example, you have collection ArrayList with elements Student class:

List stuList = new ArrayList();
Student s1 = new Student("Raju");
Student s2 = new Student("Harish");
stuList.add(s1);
stuList.add(s2);
//now you can convert this collection stuList to Array like this
Object[] stuArr = stuList.toArray();           // <----- toArray() function will convert collection to array

a {
    target-name: new;
    target-new: tab;
}

The target-new property specifies whether new destination links should open in a new window or in a new tab of an existing window.

Note: The target-new property only works if the target-name property creates a new tab or a new window.

Use a progress bar with the style set to Marquee. This represents an indeterminate progress bar.

myProgressBar.Style = ProgressBarStyle.Marquee;

You can also use the MarqueeAnimationSpeed property to set how long it will take the little block of color to animate across your progress bar.

Hej man, why are you using this ?

dir /s/b/o:gn > f.txt (wrong one)

Don't you know what is that 'g' in '/o' ??

Check this out: http://www.computerhope.com/dirhlp.htm or dir /? for dir help

You should be using this instead:

dir /s/b/o:n > f.txt (right one)

From the terminal (osx) I usually use

cordova plugin -l | xargs cordova plugins rm

Pipe, pipe everything!

To expand a bit: this command will loop through the results of cordova plugin -l and feed it to cordova plugins rm.

xargs is one of those commands that you wonder why you didn't know about before. See this tut.

This doesn't work for a fact:

$table->timestamp('created_at')->default('CURRENT_TIMESTAMP');

It doesn't remove the 'default 0' that seems to come with selecting timestamp and it just appends the custom default. But we kind of need it without the quotes. Not everything that manipulates a DB is coming from Laravel4. That's his point. He wants custom defaults on certain columns like:

$table->timestamps()->default('CURRENT_TIMESTAMP');

I don't think it's possible with Laravel. I've been searching for an hour now to see whether it's possible.

Update: Paulos Freita's answer shows that it is possible, but the syntax isn't straightforward.

Make the value of first item of selection box to blank.

So when every you post the FORM you get blank value and using this way you would know that user hasn't selected anything from dropdown.

<select name="user_role" required>
    <option value="">-Select-</option>
    <option value="User">User</option>
    <option value="Admin">Admin</option>
</select>

sample code:

Ignoring the refactoring issues, you need to understand functions and return values. You don't need a global at all. Ever. You can do this:

def rps():
    # Code to determine if player wins
    if player_wins:
        return True

    return False

Then, just assign a value to the variable outside this function like so:

player_wins = rps()

It will be assigned the return value (either True or False) of the function you just called.

After the comments, I decided to add that idiomatically, this would be better expressed thus:

 def rps(): 
     # Code to determine if player wins, assigning a boolean value (True or False)
     # to the variable player_wins.

     return player_wins

 pw = rps()

This assigns the boolean value of player_wins (inside the function) to the pw variable outside the function.

You may have forgotten to define the Content-Type header. For example:

  return {
    statusCode: 200,
    headers: {
      'Content-Type': 'application/json',
    },
    body: JSON.stringify({ items }),
  }

Visual Studio 2003 - 2008 (Visual C++ 7.1 - 9) don't claim to be C99 compatible. (Thanks to rdentato for his comment.)

First one is a syntax error. Maybe you meant the difference between

const char * mychar

and

char * const mychar

In that case, the first one is a pointer to data that can't change, and the second one is a pointer that will always point to the same address.

I tried findAndModify() to update a particular field in a pre-existing object.

https://docs.mongodb.com/manual/reference/method/db.collection.findAndModify/

Either move the xyz.h file somewhere else so the preprocessor can find it, or else change the #include statement so the preprocessor finds it where it already is.

Where the preprocessor looks for included files is described here. One solution is to put the xyz.h file in a folder where the preprocessor is going to find it while following that search pattern.

Alternatively you can change the #include statement so that the preprocessor can find it. You tell us the xyz.cxx file is is in the 'code' folder but you don't tell us where you've put the xyz.h file. Let's say your file structure looks like this...

<some folder>\xyz.h
<some folder>\code\xyz.cxx

In that case the #include statement in xyz.cxx should look something like this..

#include "..\xyz.h"

On the other hand let's say your file structure looks like this...

<some folder>\include\xyz.h
<some folder>\code\xyz.cxx

In that case the #include statement in xyz.cxx should look something like this..

#include "..\include\xyz.h"

Update: On the other other hand as @In silico points out in the comments, if you are using #include <xyz.h> you should probably change it to #include "xyz.h"

You can also use DBMS_METADATA:

select dbms_metadata.get_ddl('FUNCTION', 'FGETALGOGROUPKEY', 'PADCAMPAIGN') 
from dual

jQuery offers the .hide() method for this purpose. Simply select the element of your choice and call this method afterward. For example:

$('#comanda').hide();

One can also determine how fast the transition runs by providing a duration parameter in miliseconds or string (possible values being 'fast', and 'slow'):

$('#comanda').hide('fast');

In case you want to do something just after the element hid, you must provide a callback as a parameter too:

$('#comanda').hide('fast', function() {
  alert('It is hidden now!');
});

You can always use

header('Location: https://www.domain.com/cart_save/');

to redirect to the save URL.

But I would recommend to do it by .htaccess and the Apache rewrite rules.

Change the order in which you are doing things just a bit. You seem to be dividing by 2 for no particular reason at all.

While your application does not guarantee an input string of semi colon delimited variables you could easily make it do so:

package com;

import java.util.Scanner;

public class Test {
    public static void main(String[] args) {
        // Good practice to initialize before use
        Scanner keyboard = new Scanner(System.in);
        String input = "";
        // it's also a good idea to prompt the user as to what is going on
        keyboardScanner : for (;;) {
            input = keyboard.next();
            if (input.indexOf(",") >= 0) { // Realistically we would want to use a regex to ensure [0-9],...etc groupings 
                break keyboardScanner;  // break out of the loop
            } else { 
                keyboard = new Scanner(System.in);
                continue keyboardScanner; // recreate the scanner in the event we have to start over, just some cleanup
            }
        }

        String strarray[] = input.split(","); // move this up here      
        int intarray[] = new int[strarray.length];

        int count = 0; // Declare variables when they are needed not at the top of methods as there is no reason to allocate memory before it is ready to be used
        for (count = 0; count < intarray.length; count++) {
            intarray[count] = Integer.parseInt(strarray[count]);
        }

        for (int s : intarray) {
            System.out.println(s);
        }
    }
}

I solved it like this;

1.Created a function

export function FormatString(str: string, ...val: string[]) {
  for (let index = 0; index < val.length; index++) {
    str = str.replace(`{${index}}`, val[index]);
  }
  return str;
}

2.Used it like the following;

FormatString("{0} is {1} {2}", "This", "formatting", "hack");

Can also use here document and vi, the below script generates a FILE.txt with 3 lines and variable interpolation

VAR=Test
vi FILE.txt <<EOFXX
i
#This is my var in text file
var = $VAR
#Thats end of text file
^[
ZZ
EOFXX

Then file will have 3 lines as below. "i" is to start vi insert mode and similarly to close the file with Esc and ZZ.

#This is my var in text file
var = Test
#Thats end of text file

paint.setStrokeWidth(3);

paint.setColor(BLACK);

and either one of your drawRect should work.

you can add this property globally in javascript:

if( navigator.userAgent.match(/iPhone|iPad|iPod/i) ) {
    var styleEl = document.createElement('style'), styleSheet;
    document.head.appendChild(styleEl);
    styleSheet = styleEl.sheet;
    styleSheet.insertRule(".modal { position:absolute; bottom:auto; }", 0);
 }

This code is easier to use:

 View rowView = listView.getChildAt(viewIndex);//The item number in the List View
    if(rowView != null)
        {
           // Your code here
        }

try like this

= IIF( MAX( iif( IsNothing(Fields!.Reading.Value ), -1, Fields!.Reading.Value ) ) = -1, "",  FormatNumber(  MAX( iif( IsNothing(Fields!.Reading.Value ), -1, Fields!.Reading.Value ), "CellReading_Reading"),3)) )

Other answers have already covered profiling to avoid premature optimization and overhead cost in parallel processing. This answer explains the ideal choice of data structures for parallel streaming.

As a rule, performance gains from parallelism are best on streams over ArrayList , HashMap , HashSet , and ConcurrentHashMap instances; arrays; int ranges; and long ranges. What these data structures have in common is that they can all be accurately and cheaply split into subranges of any desired sizes, which makes it easy to divide work among parallel threads. The abstraction used by the streams library to perform this task is the spliterator , which is returned by the spliterator method on Stream and Iterable.

Another important factor that all of these data structures have in common is that they provide good-to-excellent locality of reference when processed sequentially: sequential element references are stored together in memory. The objects referred to by those references may not be close to one another in memory, which reduces locality-of-reference. Locality-of-reference turns out to be critically important for parallelizing bulk operations: without it, threads spend much of their time idle, waiting for data to be transferred from memory into the processor’s cache. The data structures with the best locality of reference are primitive arrays because the data itself is stored contiguously in memory.

    private void TurnOnAutocomplete()
    {
        textBox.AutoCompleteMode = AutoCompleteMode.SuggestAppend;
        textBox.AutoCompleteSource = AutoCompleteSource.CustomSource;
        AutoCompleteStringCollection collection = new AutoCompleteStringCollection();
        string[] arrayOfWowrds = new string[];

        try
        {
            //Read in data Autocomplete list to a string[]
            string[] arrayOfWowrds = new string[];
        }
        catch (Exception err)
        {
            MessageBox.Show(err.Message, "File Missing", MessageBoxButtons.OK, MessageBoxIcon.Error);
        }

        collection.AddRange(arrayOFWords);
        textBox.AutoCompleteCustomSource = collection;
    }

You only need to call this once after you have your data needed for the autocomplete list. Once bound it stays with the textBox. You do not need to or want to call it every time the text is changed in the textBox, that will kill your program.

function setDate(){
    var now = new Date();
    now.setMinutes(now.getMinutes() - now.getTimezoneOffset());
    var timeToSet = now.toISOString().slice(0,16);

    /*
        If you have an element called "eventDate" like the following:

        <input type="datetime-local" name="eventdate" id="eventdate" />

        and you would like to  set the current and minimum time then use the following:
    */

    var elem = document.getElementById("eventDate");
    elem.value = timeToSet;
    elem.min = timeToSet;
}

Also, you can display current position by "drag" listener and write it to visible or hidden field. You may also need to store zoom. Here's copy&paste from working tool:

            function map_init() {
            var lt=48.451778;
            var lg=31.646305;

            var myLatlng = new google.maps.LatLng(lt,lg);
            var mapOptions = {
                center: new google.maps.LatLng(lt,lg),
                zoom: 6,
                mapTypeId: google.maps.MapTypeId.ROADMAP
            };

            var map = new google.maps.Map(document.getElementById('map'),mapOptions);   
            var marker = new google.maps.Marker({
                position:myLatlng,
                map:map,
                draggable:true
            });

            google.maps.event.addListener(
                marker,
                'drag',
                function() {
                    document.getElementById('lat1').innerHTML = marker.position.lat().toFixed(6);
                    document.getElementById('lng1').innerHTML = marker.position.lng().toFixed(6);
                    document.getElementById('zoom').innerHTML = mapObject.getZoom();

                    // Dynamically show it somewhere if needed
                    $(".x").text(marker.position.lat().toFixed(6));
                    $(".y").text(marker.position.lng().toFixed(6));
                    $(".z").text(map.getZoom());

                }
            );                  
            }

You need to import ProductName-Swift.h. Note that it's the product name - the other answers make the mistake of using the class name.

This single file is an autogenerated header that defines Objective-C interfaces for all Swift classes in your project that are either annotated with @objc or inherit from NSObject.

Considerations:

• If your product name contains spaces, replace them with underscores (e.g. My Project becomes My_Project-Swift.h)

• If your target is a framework, you need to import <ProductName/ProductName-Swift.h>

• Make sure your Swift file is member of the target

I was trying to do the same thing. While background-color and background-image exist on separate layers within an object -- meaning they can co-exist -- CSS gradients seem to co-opt the background-image layer.

From what I can tell, border-image seems to have wider support than multiple backgrounds, so maybe that's an alternative approach.

UPDATE: A bit more research. Seems Petra Gregorova has something working here --> http://petragregorova.com/demos/css-gradient-and-bg-image-final.html

Enter the original date into a Date object and then print out the result with a DateFormat. You may have to split up the string into smaller pieces to create the initial Date object, if the automatic parse method does not accept your format.

Pseudocode:

Date inputDate = convertYourInputIntoADateInWhateverWayYouPrefer(inputString);
DateFormat outputFormat = new SimpleDateFormat("MM/dd/yyyy hh:mm:ss.SSS");
String outputString = outputFormat.format(inputDate);

I use Eclipse Java EE edition

Create a "Dynamic Web Project"

Install a local server in the server view, for the version of Tomcat I'm using. Then debug, and run on that server for testing.

When I deploy I export the project to a war file.

Because of double print function. I suggest you to use return instead of print inside the function definition.

def lyrics():
    return "The very first line"
print(lyrics())

OR

def lyrics():
    print("The very first line")
lyrics()

You can also used below code

<html>
<head>
    <style>
        .labelClass{
            float: left;
            width: 113px;
        }
    </style>
</head>
<body>
  <form action="yourclassName.jsp">
    <span class="labelClass">First name: </span><input type="text" name="fname"><br>
    <span class="labelClass">Last name: </span><input type="text" name="lname"><br>
    <input type="submit" value="Submit">
  </form>

It looks like you might have inserted an extra + at the beginning of each line, which R is interpreting as a unary operator (like - interpreted as negation, rather than subtraction). I think what will work is

ggplot(combined.data, aes(x = region, y = expression, fill = species)) +
    geom_boxplot() +
    scale_fill_manual(values = c("yellow", "orange")) + 
    ggtitle("Expression comparisons for ACTB") + 
    theme(axis.text.x = element_text(angle=90, face="bold", colour="black"))

Perhaps you copy and pasted from the output of an R console? The console uses + at the start of the line when the input is incomplete.

Instead of recursive CTEs and while loops, has anyone considered a more set-based approach? Note that this function was written for the question, which was based on SQL Server 2008 and comma as the delimiter. In SQL Server 2016 and above (and in compatibility level 130 and above), STRING_SPLIT() is a better option.

CREATE FUNCTION dbo.SplitString
(
  @List     nvarchar(max),
  @Delim    nvarchar(255)
)
RETURNS TABLE
AS
  RETURN ( SELECT [Value] FROM 
  ( 
    SELECT [Value] = LTRIM(RTRIM(SUBSTRING(@List, [Number],
      CHARINDEX(@Delim, @List + @Delim, [Number]) - [Number])))
    FROM (SELECT Number = ROW_NUMBER() OVER (ORDER BY name)
      FROM sys.all_columns) AS x WHERE Number <= LEN(@List)
      AND SUBSTRING(@Delim + @List, [Number], DATALENGTH(@Delim)/2) = @Delim
    ) AS y
  );
GO

If you want to avoid the limitation of the length of the string being <= the number of rows in sys.all_columns (9,980 in model in SQL Server 2017; much higher in your own user databases), you can use other approaches for deriving the numbers, such as building your own table of numbers. You could also use a recursive CTE in cases where you can't use system tables or create your own:

CREATE FUNCTION dbo.SplitString
(
  @List     nvarchar(max),
  @Delim    nvarchar(255)
)
RETURNS TABLE WITH SCHEMABINDING
AS
   RETURN ( WITH n(n) AS (SELECT 1 UNION ALL SELECT n+1 
       FROM n WHERE n <= LEN(@List))
       SELECT [Value] = SUBSTRING(@List, n, 
       CHARINDEX(@Delim, @List + @Delim, n) - n)
       FROM n WHERE n <= LEN(@List)
      AND SUBSTRING(@Delim + @List, n, DATALENGTH(@Delim)/2) = @Delim
   );
GO

But you'll have to append OPTION (MAXRECURSION 0) (or MAXRECURSION <longest possible string length if < 32768>) to the outer query in order to avoid errors with recursion for strings > 100 characters. If that is also not a good alternative then see this answer as pointed out in the comments.

(Also, the delimiter will have to be NCHAR(<=1228). Still researching why.)

I want to be able to close an alert box automatically using javascript after a certain amount of time or on a specific event (i.e. onkeypress)

A sidenote: if you have an Alert("data"), you won't be able to keep code running in background (AFAIK)... . the dialog box is a modal window, so you can't lose focus too. So you won't have any keypress or timer running...

Function is symmetric for values of type list; Tuples are coverted to lists when performing reverse_dict(reverse_dict(dictionary))

def reverse_dict(dictionary):
    reverse_dict = {}
    for key, value in dictionary.iteritems():

            value = [value]
        for val in value:

            reverse_dict[val].append(key)
    for key, value in reverse_dict.iteritems():
        if len(value) == 1:
            reverse_dict[key] = value[0]
    return reverse_dict

$observe() is a method on the Attributes object, and as such, it can only be used to observe/watch the value change of a DOM attribute. It is only used/called inside directives. Use $observe when you need to observe/watch a DOM attribute that contains interpolation (i.e., {{}}'s).
E.g., attr1="Name: {{name}}", then in a directive: attrs.$observe('attr1', ...).
(If you try scope.$watch(attrs.attr1, ...) it won't work because of the {{}}s -- you'll get undefined.) Use $watch for everything else.

$watch() is more complicated. It can observe/watch an "expression", where the expression can be either a function or a string. If the expression is a string, it is $parse'd (i.e., evaluated as an Angular expression) into a function. (It is this function that is called every digest cycle.) The string expression can not contain {{}}'s. $watch is a method on the Scope object, so it can be used/called wherever you have access to a scope object, hence in

• a controller -- any controller -- one created via ng-view, ng-controller, or a directive controller
• a linking function in a directive, since this has access to a scope as well

Because strings are evaluated as Angular expressions, $watch is often used when you want to observe/watch a model/scope property. E.g., attr1="myModel.some_prop", then in a controller or link function: scope.$watch('myModel.some_prop', ...) or scope.$watch(attrs.attr1, ...) (or scope.$watch(attrs['attr1'], ...)).
(If you try attrs.$observe('attr1') you'll get the string myModel.some_prop, which is probably not what you want.)

As discussed in comments on @PrimosK's answer, all $observes and $watches are checked every digest cycle.

Directives with isolate scopes are more complicated. If the '@' syntax is used, you can $observe or $watch a DOM attribute that contains interpolation (i.e., {{}}'s). (The reason it works with $watch is because the '@' syntax does the interpolation for us, hence $watch sees a string without {{}}'s.) To make it easier to remember which to use when, I suggest using $observe for this case also.

To help test all of this, I wrote a Plunker that defines two directives. One (d1) does not create a new scope, the other (d2) creates an isolate scope. Each directive has the same six attributes. Each attribute is both $observe'd and $watch'ed.

<div d1 attr1="{{prop1}}-test" attr2="prop2" attr3="33" attr4="'a_string'"
        attr5="a_string" attr6="{{1+aNumber}}"></div>

Look at the console log to see the differences between $observe and $watch in the linking function. Then click the link and see which $observes and $watches are triggered by the property changes made by the click handler.

Notice that when the link function runs, any attributes that contain {{}}'s are not evaluated yet (so if you try to examine the attributes, you'll get undefined). The only way to see the interpolated values is to use $observe (or $watch if using an isolate scope with '@'). Therefore, getting the values of these attributes is an asynchronous operation. (And this is why we need the $observe and $watch functions.)

Sometimes you don't need $observe or $watch. E.g., if your attribute contains a number or a boolean (not a string), just evaluate it once: attr1="22", then in, say, your linking function: var count = scope.$eval(attrs.attr1). If it is just a constant string – attr1="my string" – then just use attrs.attr1 in your directive (no need for $eval()).

See also Vojta's google group post about $watch expressions.

You can select directly into the variable rather than using set:

DECLARE @times int

SELECT @times = COUNT(DidWin)
FROM thetable
WHERE DidWin = 1 AND Playername='Me'

If you need to set multiple variables you can do it from the same select (example a bit contrived):

DECLARE @wins int, @losses int

SELECT @wins = SUM(DidWin), @losses = SUM(DidLose)
FROM thetable
WHERE Playername='Me'

If you are partial to using set, you can use parentheses:

DECLARE @wins int, @losses int

SET (@wins, @losses) = (SELECT SUM(DidWin), SUM(DidLose)
FROM thetable
WHERE Playername='Me');

I've tried different ways of blocking scrolling when the arrow keys are pressed, both jQuery and native Javascript - they all work fine in Firefox, but don't work in recent versions of Chrome.
Even the explicit {passive: false} property for window.addEventListener, which is recommended as the only working solution, for example here.

In the end, after many tries, I found a way that works for me in both Firefox and Chrome:

window.addEventListener('keydown', (e) => {
    if (e.target.localName != 'input') {   // if you need to filter <input> elements
        switch (e.keyCode) {
            case 37: // left
            case 39: // right
                e.preventDefault();
                break;
            case 38: // up
            case 40: // down
                e.preventDefault();
                break;
            default:
                break;
        }
    }
}, {
    capture: true,   // this disables arrow key scrolling in modern Chrome
    passive: false   // this is optional, my code works without it
});

Quote for EventTarget.addEventListener() from MDN

options Optional
   An options object specifies characteristics about the event listener. The available options are:

capture
   A Boolean indicating that events of this type will be dispatched to the registered listener before being dispatched to any EventTarget beneath it in the DOM tree.
once
   ...
passive
   A Boolean that, if true, indicates that the function specified by listener will never call preventDefault(). If a passive listener does call preventDefault(), the user agent will do nothing other than generate a console warning. ...

It's not a matter of pixels count, it's a matter of actual size (in mm or inches) of characters on the screen, which depends on pixels density. Hence "min-width:" and "max-width:" are useless. A full explanation of this issue is here: what exactly is device pixel ratio?

"@media" queries take into account the pixels count and the device pixel ratio, resulting in a "virtual resolution" which is what you have to actually take into account while designing your page: if your font is 10px fixed-width and the "virtual horizontal resolution" is 300 px, 30 characters will be needed to fill a line.

After changing language newly created activities display with changed new language, but current activity and previously created activities which are in pause state are not updated.How to update activities ?

Pre API 11 (Honeycomb), the simplest way to make the existing activities to be displayed in new language is to restart it. In this way you don't bother to reload each resources by yourself.

private void restartActivity() {
    Intent intent = getIntent();
    finish();
    startActivity(intent);
}

Register an OnSharedPreferenceChangeListener, in its onShredPreferenceChanged(), invoke restartActivity() if language preference was changed. In my example, only the PreferenceActivity is restarted, but you should be able to restart other activities on activity resume by setting a flag.

Update (thanks @stackunderflow): As of API 11 (Honeycomb) you should use recreate() instead of restartActivity().

public class PreferenceActivity extends android.preference.PreferenceActivity implements
        OnSharedPreferenceChangeListener {

    // ...

    @Override
    public void onSharedPreferenceChanged(SharedPreferences sharedPreferences, String key) {
        if (key.equals("pref_language")) {
            ((Application) getApplication()).setLocale();
            restartActivity();
        }
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        addPreferencesFromResource(R.xml.preferences);
        getPreferenceScreen().getSharedPreferences().registerOnSharedPreferenceChangeListener(this);
    }

    @Override
    protected void onStop() {
        super.onStop();
        getPreferenceScreen().getSharedPreferences().unregisterOnSharedPreferenceChangeListener(this);
    }
}

I have a blog post on this topic with more detail, but it's in Chinese. The full source code is on github: PreferenceActivity.java

The classic need for GOTO in C is as follows

for ...
  for ...
    if(breakout_condition) 
      goto final;

final:

There is no straightforward way to break out of nested loops without a goto.

Just in case someone wants to do that in PHP I posted a gist on Github

https://gist.github.com/redestructa/2a7691e7f3ae69ec5161220c99e2d1b3

simply call:

$output = $tablePrinter->printLinesIntoArray($items, ['title', 'chilProp2']);

you may need to adapt the code if you are using a php version older than 7.2

after that call echo or writeLine depending on your environment.

You could use PHP's dirname function. <?php echo dirname(__DIR__); ?>. That will give you the name of the parent directory of __DIR__, which stores the current directory.

Using indexOf and Recursion:

First check if the nth position passed is greater than the total number of substring occurrences. If passed, recursively go through each index until the nth one is found.

var getNthPosition = function(str, sub, n) {
    if (n > str.split(sub).length - 1) return -1;
    var recursePosition = function(n) {
        if (n === 0) return str.indexOf(sub);
        return str.indexOf(sub, recursePosition(n - 1) + 1);
    };
    return recursePosition(n);
};

You May use set keyword for set the path

set path=%path%;c:/wamp/bin/php/php5.3.0

if all the path are set in path variables

If you want to see all path list. you can use

set %path%

you need to append your php path behind this path.

This is how you can set environment variable.

Have you tried using an absolute path:

File file = new File(System.getProperty("user.dir") + "/file.txt");

you can use skimage.img_as_ubyte(yourdata) it will make you numpy array ranges from 0->255

from skimage import img_as_ubyte

img = img_as_ubyte(data)
cv2.imshow("Window", img)

First, have you compiled the class using the command line javac compiler? Second, it seems that your main method has an incorrect signature - it should be taking in an array of String objects, rather than just one:

public static void main(String[] args){

Once you've changed your code to take in an array of String objects, then you need to make sure that you're printing an element of the array, rather than array itself:

System.out.println(args[0])

If you want to print the whole list of command line arguments, you'd need to use a loop, e.g.

for(int i = 0; i < args.length; i++){
    System.out.print(args[i]);
}
System.out.println();

You may find my MSDN article on the subject helpful; I took a lot of space in that article describing when you should use async on ASP.NET, not just how to use async on ASP.NET.

I have some concerns using async actions in ASP.NET MVC. When it improves performance of my apps, and when - not.

First, understand that async/await is all about freeing up threads. On GUI applications, it's mainly about freeing up the GUI thread so the user experience is better. On server applications (including ASP.NET MVC), it's mainly about freeing up the request thread so the server can scale.

In particular, it won't:

• Make your individual requests complete faster. In fact, they will complete (just a teensy bit) slower.
• Return to the caller/browser when you hit an await. await only "yields" to the ASP.NET thread pool, not to the browser.

First question is - is it good to use async action everywhere in ASP.NET MVC?

I'd say it's good to use it everywhere you're doing I/O. It may not necessarily be beneficial, though (see below).

However, it's bad to use it for CPU-bound methods. Sometimes devs think they can get the benefits of async by just calling Task.Run in their controllers, and this is a horrible idea. Because that code ends up freeing up the request thread by taking up another thread, so there's no benefit at all (and in fact, they're taking the penalty of extra thread switches)!

Shall I use async/await keywords when I want to query database (via EF/NHibernate/other ORM)?

You could use whatever awaitable methods you have available. Right now most of the major players support async, but there are a few that don't. If your ORM doesn't support async, then don't try to wrap it in Task.Run or anything like that (see above).

Note that I said "you could use". If you're talking about ASP.NET MVC with a single database backend, then you're (almost certainly) not going to get any scalability benefit from async. This is because IIS can handle far more concurrent requests than a single instance of SQL server (or other classic RDBMS). However, if your backend is more modern - a SQL server cluster, Azure SQL, NoSQL, etc - and your backend can scale, and your scalability bottleneck is IIS, then you can get a scalability benefit from async.

Third question - How many times I can use await keywords to query database asynchronously in ONE single action method?

As many as you like. However, note that many ORMs have a one-operation-per-connection rule. In particular, EF only allows a single operation per DbContext; this is true whether the operation is synchronous or asynchronous.

Also, keep in mind the scalability of your backend again. If you're hitting a single instance of SQL Server, and your IIS is already capable of keeping SQLServer at full capacity, then doubling or tripling the pressure on SQLServer is not going to help you at all.

Exactly same problem. Tried kill and start but what this worked for me:

adb reconnect

Hope it helps.

Windows

On Windows you need to include the gl.h header for OpenGL 1.1 support and link against OpenGL32.lib. Both are a part of the Windows SDK. In addition, you might want the following headers which you can get from http://www.opengl.org/registry .

• <GL/glext.h> - OpenGL 1.2 and above compatibility profile and extension interfaces..
• <GL/glcorearb.h> - OpenGL core profile and ARB extension interfaces, as described in appendix G.2 of the OpenGL 4.3 Specification. Does not include interfaces found only in the compatibility profile.
• <GL/glxext.h> - GLX 1.3 and above API and GLX extension interfaces.
• <GL/wglext.h> - WGL extension interfaces.

Linux

On Linux you need to link against libGL.so, which is usually a symlink to libGL.so.1, which is yet a symlink to the actual library/driver which is a part of your graphics driver. For example, on my system the actual driver library is named libGL.so.256.53, which is the version number of the nvidia driver I use. You also need to include the gl.h header, which is usually a part of a Mesa or Xorg package. Again, you might need glext.h and glxext.h from http://www.opengl.org/registry . glxext.h holds GLX extensions, the equivalent to wglext.h on Windows.

If you want to use OpenGL 3.x or OpenGL 4.x functionality without the functionality which were moved into the GL_ARB_compatibility extension, use the new gl3.h header from the registry webpage. It replaces gl.h and also glext.h (as long as you only need core functionality).

Last but not the least, glaux.h is not a header associated with OpenGL. I assume you've read the awful NEHE tutorials and just went along with it. Glaux is a horribly outdated Win32 library (1996) for loading uncompressed bitmaps. Use something better, like libPNG, which also supports alpha channels.
